FORGE.

SPECIPIC'ATIQN forming part of Letters Patent No. 326,588, dated September 22, 1885.

Application filed October 4,1884. (No model.)

To all whom it may concern.-

I Be it known that I, HIRAM W. RANSOM, of the city of Cincinnati, in the county of Harnilton and State of Ohio, have invented certain new and useful Improvements in Blacksmith- Forges, of which the following is a specification.

The object of my invention is to provide a cheap, simple, and compact and very durable forge, by the aid of which all kinds of blacksmithing can be done conveniently, and which shall save fuel and produce a very uniform and strong heat.

The several features of my invention and their use, conj oint] y or otherwise, will be fully apparent from the following description and claims.

In the accompanying drawings, Figure 1 represents a top view of a forge illustrating my invention, part of the lining in the firechamber being removed to show the tuyereplate and my improved mode of constructing it to receive the lining. Fig. 2 is a transverse vertical section taken at the line :0 m of Fig. 1. Fig. 3 is an enlarged transverse cross-section through the fire-box and tuyere and connections,taken at the line y y of Fig. 1. Fig. 4 is a view of the rear or outside of one of the lining-plates for the fire-chamber.

A represents a forge-plate of suitable size, on which the iron to be heated, and fuel for the fire, and tools for use are usually to be placed. This plate has its edges 0 turned up, and is suitably mounted or supported,preferably upon legs, as a, one of such legs being bolted or otherwise secured at each corner of the plate by the bolt-and-nut connection a. These legs are preferably fastened by any efficient means to the floor or place where the forge is to be used. At any suitable portion of this plate A, preferably near one of the corners, is located the fire chamber or box A.

This fire-chamber begins at or about in aplane with the top of the said forge plate or table A, and extends downward. This chamber has walls a preferably four in number, which taper down toward the plate B. Each one of these walls a is provided with and covered by a lining, a.

The outer or rear surface of linings.

of a metallic plate-this plate is preferably separated from the wall a of the furnace-chamber by an inter-space, and the latter may be filled with brick, clay, asbestos, or some other suitable materialwhich is to some extent a non-conductor of heat, Ordinarily this interspace is preferably left unfilled, and the air present therein and circulating operates to keep the lining-plate cool and prevent the latter from warping. The presence of this interspace enables the linings to be more conveniently removed and replaced or renewed. Where there is an interspace between the lining and wall a a convenient mode of keeping the lining from the wall consists in providing the lining with ribs or projections a, which latter rest against the sides or walls of the fire-chamber and support their respective This makes a fire-chamber that re tains the heat, saves fuel, and heats the iron quickly and thoroughly.

B represents the tuyere, which is situated below the fire-chamber A, with its mouth 1) opening into the bottom of said fire-chamber. Through this tuyere the blast enters the firechamber A. The tuyere-plate 13 consists of the bottom portion,b, and the raised portion 2). Through the partb of this plate and the bottom portion, 12 of the fire-chamber pass bolts b, which receive nuts I) on theirlower ends, and thus tightly hold the tuyere to the fire-chamber.

The peculiar construction of the tuyereplate B answers two objects, viz: first, its wings or parts 1) form a convenient means for connecting the tuyere to the fire-chamber; second, the part b of the plate being raised somewhat above the part b, the latter forms a convenient seat for the lining-plate a, while the side or vertical face of the part 1; forms a shoulder, against which latter receives the side of the lower portions of the lining, and assists in retaining the said linings in position.

The tuyere is preferably furnished with a suitable device for shaking down the ashes. A desirable form of such device is the following well-known one, viz: WVithin the tuyere,

and just below the contracted portion thereof, is the short bar or knocker D. This bar or knocker is usually triangular in shape, with its corners slightly dull and rounded, and is so situated in the tuyere as that its corners d extend a slight distance up into the contracted neck or mouth of the tuyere and strike the cinders or ashes in the bottom of the firechamber A, and allow said ashes or cinders to pass between this short bar or knocker D and the sides of the tuyere and fall onto the sliding door D, when the said short bar or knocker D is revolved or turned by the operator by suitable means, preferably by the handle D, which latter extends out to the edge of the forge, so that it can be easily reached by the operator and turned by him when necessary. This bar or knocker D is rigidly attached on the end of the long arm d of this handle D and the long arm cl of this handle is journaled at d d in the sides O of the tuyere.

A suitable device for dropping the ashes may be employed, and the following wellknown device is shown in connection with the forge: A sliding door, D, covers the bottom of the tuyere, and having upon its under side two ribs, 0 e. The sliding door D has secured to it, at e, the pull-handle E, by means of which the door D is slid forward or backward, and when pulled forward the ashes which are lying on it drop to the floor or into a receptacle placed under the forge.

A gnidebar, E, is secured at the bottom of the tuyere below the sliding door D. One end of the guide-bar E is suitably secured to the side 0 of the tuyere, and, running along under the door D, forms a guide upon which the door D, by means of the ribs 0 0, slides. The guide'bar also has the hook or projection E",which contains at e a hole, through which the pull-handle E passes, and forms a guide and support for said handle E. The upper or free end of this guide book or projection E is secured, at .n, to the side 0 of the tuyere.

A pipe, F, leads from a bellows or other suitable air-supply to the tuyere B. V The air passing into the tuyere through this pipe may be regulated, as isusual in such instances, by a valve or othersuitable device placed at any convenient point. the pipe E, after the valve has been opened, rushes into the tuyere B and creates a blast, which passes up and out of the tuyere, and strikes the burning fuel in the fire-chamber A. When the ashes have accumulated in the fire-chamber A, the handle D is turned, and the bar or knocker D strikes the ashes and they descend, and, after passing said bar, fall upon the sliding door D. The opera-tor then pulls the handle E, and the ashes are precipiated upon the floor or ground. The pressure of the bar D in the tuyere also regulates the blast.

The entire forge is usually and preferably constructed of iron, but may be made of any other suitable material. The forge-plate A The air passing through and the firebox A are -preferably cast in one piece. The tuyere B and its plate B and pipe F are preferably made in one piece.

The upright portion 1)" of the tuyere and the ledge I) of the same afford a secure foothold for the lining, whether same be of brick, clay, 850., or a metal plate, or both metal and clay, brick, asbestns, &c. The upright portion or extension b of said tuyere also takes the fierce heat of the furnace, and prevents the lower portions of the tuyere from warping or burning out.

While the various features of my invention are preferably used together, one or more of said features may be used without the remainder, and one or more of said features may, so far as applicable, be employed in connection with forges other than the one herein specifically set forth.

What I claim as new, and desire to secure by.Letters Patent, is-
